Detailed Implementation

[0024] The following is a clear and complete description. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This embodiment proposes a cleaning agent, which, by weight, consists of the following components: 3-5 alkyl glycosides, 0.1-0.3 tea saponins, 3-5 sodium citrate, 1-3 sodium polyaspartate, 7-10 fatty acid methyl ester polyoxyethylene ether, 3-5 C2-C4 alcohols, 0.1-0.3 alkaline pH adjuster, and the balance being water.

[0026] Among them, C2-C4 alcohol can be one of ethanol, n-propanol, and isopropanol, with ethanol being preferred; alkaline pH adjuster can be potassium hydroxide, sodium carbonate, ammonia (NH3·H2O), sodium bicarbonate (NaHCO3), etc., with sodium hydroxide being preferred; alkyl glycoside can be of models such as APG0810, APG1214, APG12, APG14, APG1618, APG16, and APG18, with APG0810 being preferred; water can be tap water, purified water, etc., with deionized water being preferred.

[0027] In this embodiment, the alkyl glycoside has detergency, emulsification, foaming, and foam stabilization functions, and is a nonionic surfactant with environmentally friendly and low-residue characteristics; tea saponin has detergency, emulsification, foaming, and antibacterial functions, and is a natural surfactant that enhances detergency; sodium citrate is a chelating agent and buffer that can soften water, prevent hard water ion precipitation, and play a certain role in pH adjustment; fatty acid methyl ester polyoxyethylene ether is used as a solvent to dissolve grease and stubborn dirt; alkaline pH adjuster is used to adjust pH and promote grease saponification; and water is used as a solvent to dilute and carry other components.

[0028] In this embodiment, surfactants are the core cleaning components, particularly the combination of alkyl glycosides and tea saponins. Alkyl glycosides, as the primary surfactant, provide excellent detergency, emulsification, and low residue properties; tea saponins, as a secondary surfactant, enhance detergency and provide natural antibacterial effects. The synergistic effect of both ensures that the glass is bright and streak-free after cleaning.

[0029] To achieve better cleaning results, the mass ratio of alkyl glycosides to tea saponins should be controlled within 10-50 times.

[0030] Preferably, the overall pH value is adjusted to 6±0.5 by the alkaline pH adjuster, making the cleaning agent generally neutral, which greatly reduces the risk of corrosion to the glass and also ensures the safety of the workers.

[0031] In one embodiment, a cleaning agent, by weight, comprises the following components: alkyl glycoside (APG0810) 3, tea saponin 0.1, sodium citrate 3, sodium polyaspartate 1, fatty acid methyl ester polyoxyethylene ether 7, ethanol 3, sodium hydroxide 0.1, and deionized water 82.8.

[0032] In another embodiment, a cleaning agent, by weight, comprises the following components: alkyl glycoside (APG0810) 5, tea saponin 0.3, sodium citrate 5, sodium polyaspartate 3, fatty acid methyl ester polyoxyethylene ether 10, ethanol 5, sodium hydroxide 0.3, and deionized water 71.4.

[0033] In another embodiment, a cleaning agent, by weight, comprises the following components: alkyl glycoside (APG0810) 4, tea saponin 0.2, sodium citrate 4, sodium polyaspartate 2, fatty acid methyl ester polyoxyethylene ether 8.5, ethanol 4, sodium hydroxide 0.2, and deionized water 77.1.

[0034] Accordingly, its preparation method is as follows:

[0035] Add the required amount of deionized water to the mixing tank and stir.

[0036] Add sodium citrate and sodium polyaspartate and stir until completely dissolved;

[0037] Add alkyl glycosides and tea saponins and stir until dissolved;

[0038] Slowly add ethanol and fatty acid methyl ester polyoxyethylene ether, and stir until transparent;

[0039] Add an alkaline pH adjuster to adjust the pH value to 6±0.5;

[0040] After standing and defoaming, the product is packaged in measured quantities.

[0041] Preferably, the stirring rate should not be too fast, and a stirring rate of 400-600 rpm should be used.

[0042] Preferably, sodium hydroxide is used as the alkaline pH adjuster.

[0043] The following are the experimental data (by weight) for the product of this application:

[0044]

[0045] In the experiments of groups 1 to 3, the alkyl glycoside APG0810 used was a product of Shanghai Fakai Chemical Co., Ltd., with a concentration of 1-10%; the tea saponin used was a product of Hunan Huano Tea Saponin Technology, with a concentration of 1-5%; the sodium citrate used was a product of Yingxuan Company, with a concentration of 1-5%; the sodium polyaspartate used was a product of Jiangsu Haian Petrochemical Plant, with a concentration of 0.5-3%; the fatty acid methyl ester polyoxyethylene ether used was a product of a biodiesel manufacturer, with a concentration of 1-5%; and the sodium hydroxide concentration was 0.1-1%.

[0046] The experimental results are as follows (corresponding to experimental data sets 1-3 in the table above):

[0047]

[0048]

[0049] The experimental data show that as the mass percentage of alkyl glycoside APG0810 increases and the mass percentage of tea saponin decreases, the cleaning effect becomes better and better.

[0050] Cleaning experiment using traditional glass cleaner (containing 10% alcohol, 5% ammonia, and 85% water):

[0051]

[0052] When comparing the cleaning effect of the product of this application with that of traditional glass cleaner (containing 10% alcohol, 5% ammonia, and 85% water), the product of this application is superior to traditional products in terms of cleaning rate, environmental friendliness, and no residue.

[0053] The beneficial effects of this invention are:

[0054] The technical solution of this invention uses a neutral and mild formula that is free of strong acids, strong alkalis, heavy metals, and fluorides. It is friendly and safe for all types of glass, including coated glass, anti-glare glass, Low-E glass, ordinary clear glass, and tempered glass. It is not prone to corrosion and is safe for workers. In addition, it is biodegradable and environmentally friendly. It is also instant brightening, with moderate cleaning power, which can quickly remove daily stains, dry quickly without watermarks, restore the glass's luster, and form a protective layer on the glass surface to delay the adhesion of dirt.

[0055] The core cleaning mechanism of this invention is as follows: surfactants (such as alkyl glycosides and tea saponins) reduce the surface tension of water, wet the glass surface, and penetrate and emulsify grease and dirt. Simultaneously, sodium citrate acts as a chelating agent to soften the water and prevent calcium and magnesium ions from forming scale; fatty acid methyl esters act as solvents to dissolve stubborn oil stains; and sodium hydroxide adjusts the pH to a slightly alkaline state, promoting the saponification of grease. Ultimately, the dirt is emulsified and dispersed in the water, and removed by rinsing or wiping.

[0056] Alkyl glycosides and tea saponins, as surfactants, complement each other to enhance detergency and foaming properties, reducing residue; sodium citrate improves water quality, prevents redeposition of dirt, and increases surfactant efficiency. The components work synergistically to enhance detergency. Therefore, it is suitable for various types of dirt (such as oil, fingerprints, and dust) and is environmentally friendly and safe.

[0057] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
